BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling structure formed of a steel ceiling frame and a ceiling suspension fitting.

[0002]

2. Description of the Related Art In general, a ceiling is connected by a hanging tree between a hanging tree support passed between beams and a field edge to which a ceiling panel is attached, and a peripheral edge of the ceiling panel is provided by a peripheral edge provided on a partition panel. Is fixed. In the case of such a ceiling structure, a hanging tree receiver is provided for each room partitioned by the partition panel,
The construction of the ceiling board, the ridge, the hanging tree, and the surroundings has to be performed, so that not only a lot of work time is required but also the cost is increased.

[0003] For this reason, the wooden beam is framed into a rectangular frame to form a panel, and the ceiling panels are connected to construct a ceiling.
It has been proposed to partition with a partition panel.
It is known that such a ceiling panel is hung on a beam with a ceiling hanging metal fitting to form a ceiling (see Japanese Patent Laid-Open No. 6-193188, which is the application of the applicant).

[0004]

However, when a ceiling is constructed using this ceiling hanging metal fitting, a notch (a gap) for inserting a hexagon wrench is required between adjacent ceiling panels, Finally, the sum of the gaps proportional to the number of ceiling panels occurs between the inner wall frame and the wall surface. Therefore, in order to construct a ceiling with an integral multiple ceiling panel, it is necessary to use a ceiling panel that has a size that takes into consideration the total amount of gaps that occur due to changes in the size of the room. There was a problem that it was difficult.

Further, as described above, since the partition panel is arranged, in order to adjust the height position of the ceiling panel with respect to the beam, the hexagon wrench is provided at the position directly below the beam through the notch formed in the panel engaging plate. It is difficult to work because it is necessary to insert the connector and rotate the connecting bolt with a hexagonal wrench, and each time one ceiling panel is installed, the panel engaging plate of the ceiling hanging metal fitting and the wooden crosspiece on one side of the ceiling panel are nailed. There was also a problem that the work had to be done by striking and fixing.

For the purpose of making the ceiling incombustible and improving the strength of the ceiling groundwork, the applicant of the present invention has filed Japanese Patent Application Laid-Open No. 6-240802.
As described in Japanese Patent Publication, it is also proposed to form a steel ceiling frame by framing a steel material in a rectangular shape, and hang the steel ceiling frame on the beam with the above-described ceiling hanging bracket to construct a ceiling. However, as long as the above ceiling hanging metal fittings are used,
We cannot solve the above problems.

The present invention has been made in view of the above problems, and provides a ceiling structure capable of forming a ceiling using a steel ceiling frame having an integral multiple of a standardized size. is there.

It has become. In addition, the side surface of the runner field edge 4 and the side surface of the field edge 5 have uneven portions (see FIG. 4).
Are formed to improve the bending strength.

The steel ceiling frame 2 has standardized vertical and horizontal dimensions so that it can be adjusted to the size of the ceiling. For example, 1 m × 2, which is almost equivalent to one tatami mat.
Plural kinds of sizes are prepared based on m.

On the other hand, the above-mentioned steel ceiling frame 2 is attached to the beam H.
The ceiling hanging metal fitting 6 which is hung on is shown in FIG.
The ceiling suspension metal fitting 6 is a suspension metal fitting 7 that can be attached to the beam H, a field edge metal fitting 8 that can be fitted into the field edge 5 that forms the framework of the steel ceiling frame 2, and a connection screwed to the suspension metal fitting 7. It is composed of a bolt 9 and a pair of nuts 10 screwed to the connecting bolt 9 and holding the field edge fitting 8 therebetween.

The hanging metal fitting 7 is bent in a U-shaped cross section, and has a notch opening 71a formed in both vertical pieces 711 so that it can be inserted into the flange h of the beam H.
And a butterfly bolt 72 located above the cutout opening 71a of the hanging metal fitting body 71 and screwed into the horizontal piece 712, and the bottom edge of the cutout opening 71a of the hanging fitting main body 71 has a saw blade shape. Has been formed. Further, on the horizontal piece 712 of the hanging fitting main body 71, a female screw 71b to which the connecting bolt 9 can be screwed by burring is formed in the vicinity of the edge facing the cutout opening 71a.

The field metal fitting 8 is a field metal fitting body 81 bent in a substantially b-shape so as to surround the outer peripheral surface of the field edge 5 forming the framework of the steel ceiling frame 2, and this field metal fitting. The vertical piece 821 is composed of an L-shaped mounting bracket 82 in which a vertical piece 821 is integrally welded to an inner vertical piece 811 of the main body 81 by spot welding. Are formed respectively. Then, the extension portion of the upper horizontal piece 812 of the main body 81 of the field metal fitting and the mounting hardware 8
The second horizontal piece 822 has holes through which the connecting bolts 9 can be inserted, and when the connecting bolts 9 are inserted into these holes, the pair of nuts 10 screwed into the connecting bolts 9 are inserted. The upper horizontal piece 812 of the field edge fitting main body 81 and the horizontal piece 822 of the mounting fitting 82 can be sandwiched and held from above and below via the. In this case, the connecting bolt 9 is arranged between the position separated from the end edge of the flange h of the beam H and the position separated from the field edge 5 forming the framework of the steel ceiling frame 2.

In order to suspend the steel ceiling frame 2 using the ceiling suspension metal fitting 6 thus constructed, first, the notch opening of the suspension metal fitting main body 71 is adjusted in accordance with the mounting height of the steel ceiling frame 2 to the beam H. The distance between the saw-toothed bottom edge of the portion 71a and the upper nut 10 is adjusted in advance. After this, the upper horizontal piece 8 of the field edge fitting body 81 in the ceiling hanging fitting 6
12 is pushed open and, as shown by the chain line in FIG. 2, it is fitted from the outside in the vicinity of the runner 3 of the field edge 5 forming the framework of the steel ceiling frame 2. Then, the connecting bolt 9 is inserted into the holes formed in the field metal fitting body 81 and the mounting metal fitting 82, and then the nut 10 is screwed into the connecting bolt 9 to mount the field metal fitting 8.

Next, after attaching a temporary fixing jig (not shown) to the flange h of the beam H, one runner 3 of the steel ceiling frame 2 is inserted into the temporary fixing jig and temporarily held,
The steel ceiling frame 2 is lifted upward around the temporary fixing jig. Then, after the other runner 3 and the runner field edge 4 that form the framework of the steel ceiling frame 2 are arranged along the marking lines that have been marked on the wall surface of the inner wall frame in advance, respectively, the other runner 3 and the runner field are formed. The edge 4 is nailed through the groove to the wall corner of the inner wall frame. The other runner 3 and runner field 4 of the steel ceiling frame 2
When the nailing is finished, the notch opening 71a of the hanging fitting body 71 of the hanging fitting 6 is inserted into the flange h of the beam H, and then the butterfly bolt 72 is tightened to fix the ceiling hanging fitting 6 to the beam H.

As a result, the three sides forming the framework of the first steel ceiling frame 2 can be supported. That is, the other runner 3 and the runner field edge 4 forming the framework of the steel ceiling frame 2 are nailed to the wall surface of the inner wall frame, and the field edge 5 forming the framework is attached to the beam H via the ceiling hanging metal fitting 6. It can be hung. After that, the temporary fixing jig is removed, and the attachment of the first steel ceiling frame 2 is completed.

Next, in order to attach the second steel ceiling frame 2, a temporary fixing jig is similarly attached to the flange h of the beam H, and one of the steel ceiling frames 2 is attached to this temporary fixing jig. Insert the runner 3 and hold it temporarily. Next, the steel ceiling frame 2 is lifted upward with a temporary fixing jig as a center, and the marking line attached to the wall surface of the inner wall frame and the field edge 5 forming the framework of the first steel ceiling frame 2 are attached. After aligning the other runner 3 and runner field edge 4 that form the framework of the second steel ceiling frame 2, the other runner 3 is used as the wall surface of the inner wall frame, and the runner field edge 4 is the first sheet. Each of the field edges 5 forming the framework of the steel ceiling frame 11 is nailed through its groove. Then, the notch opening 71a of the hanging fitting body 71 in the hanging fitting 6 is made into the beam H.
After being inserted into the flange h, the butterfly bolt 72 is tightened to fix the ceiling hanging metal fitting 6 to the beam H. As a result, the other runner 3 forming the framework of the second steel ceiling frame 2 is nailed to the wall surface of the inner wall frame, and the runner edge 4
Is nailed to the field edge 5 forming the framework of the first steel ceiling frame 2, and the field edge 5 is further hung from the beam H via the ceiling hanging metal fitting 6. After that, the temporary fixing jig is removed, and the attachment of the second steel ceiling frame 2 is completed.

Similarly, with respect to the third and subsequent steel ceiling frames 2, the other runner 3 and runner field edge 4 forming the framework of the steel ceiling frame 2 and the marking line attached to the wall surface of the inner wall frame and the preceding stage, respectively. The field edge 5 forming the framework of the steel ceiling frame 2 is nailed, and the field edge 5 forming the framework of the steel ceiling frame 2 is suspended on the beam H via the ceiling suspension metal fitting 6. When reaching the wall surface corner of the other inner wall frame, the field edge 5 forming the frame of the steel ceiling frame 2 may be nailed to the wall surface of the inner wall frame.

When the steel ceiling frame 2 is constructed in this manner, the thin plate-like vertical piece of the field edge metal fitting body 81 of the field edge metal fitting 8 is merely interposed between the adjacent steel ceiling frames 2. , The steel ceiling frames 2 adjacent to each other are closely connected without generating a gap. Therefore, the ceiling can be formed by the steel ceiling frame 2 that is an integral multiple of the standardized size in consideration of the wall spacing of the inner wall frame.

If a mounting error occurs, loosen the screw to release the fixation between the runner 3 and the field edge 5, and then
The field edge 5 may be moved so as to be in close contact with the wall surface of the inner wall frame with respect to the runner 3 and nailed, and a screw may be driven between the runner 3 and the runner 3 and fixed.

Similarly, the second-row steel ceiling frame 2 is also nailed and fixed. When constructing the steel ceiling frame 2 of the second row, the other runner 3 forming the framework is the one runner 3 forming the framework of the steel ceiling frame 2 of the first row constructed earlier. It is nailed.

After the ceiling is constructed in this way, the partition panel is arranged. Therefore, when adjusting the ceiling height from the floor, the groove formed at the lower end of the connecting bolt 9 is adjusted to the set dimension. By inserting a screwdriver into and rotating the screw, the connecting bolt 9 is moved up and down with respect to the hanging metal fitting 7 attached to the beam H, and the lower nut 10 is positioned. When the adjustment of the ceiling height is completed, at any position on the lower surface of the steel ceiling frame 2, for example, orthogonal to the field edge 5 or directly below the field edge 5, and further,
After placing the head joint 11 at a position directly below the field edge 5 slid with respect to the runner 3 and nailing it to the field edge 5, a partition panel 12 is applied to the floor panel (not shown), the head joint 11 and the inner wall frame. The partition wall 12 or the adjacent partition panel 12 is nailed to partition. After that, the upper nut 10 is tightened, and the field edge fitting 8 is sandwiched by the pair of nuts 10 and held between them, so that it can be fixed to the adjusted ceiling height. Furthermore, the ceiling board 13 and the inner wall board 1
4 may be attached to the wall surfaces of the steel ceiling frame 2 and the inner wall frame and the partition panel 12, respectively.

On the back surface of each steel ceiling frame 2,
A heat insulating material 15 is laid according to the size of the steel ceiling frame 2 to ensure the heat insulating property of the ceiling portion.

As described above, the runner 3 and the runner field 4 forming the framework of the steel ceiling frame 2 are sequentially fixed to the inner wall frame or the adjacent steel ceiling frame 2 and the framework of the steel ceiling frame 2 is formed. Since the ceiling can be formed by suspending the hanging edge 5 on the beam H with the ceiling hanging metal fitting 6, labor can be saved.
At this time, the adjacent steel ceiling frames 2 can be closely connected without generating a gap, and the ceiling can be constructed with the steel ceiling frames 2 having an integral multiple of a standardized size in advance. . Further, since the partition panel 12 is arranged, in order to adjust the height position of the steel ceiling frame 2 with respect to the beam H, inside the steel ceiling frame 2,
After rotating the connecting bolt 9 using the space formed between the field edges 5, the nut 10 may be tightened, and the work can be performed in a comfortable posture. Furthermore, steel ceiling frame 2
The ceiling hanging metal fitting 6 can be attached by previously fitting the field metal fitting 8 in advance and screwing the nut 10 to the connecting bolt 9 inserted into the field metal fitting 8, so that nailing work is unnecessary and the work is simple. Can be transformed.
